SPECIFICATION forming part of Letters Patent No. 432,487, dated July 15, 1890.

Application filed April 8, 1890. Serial No. 3 l7,031. (N model.)

To all whom it may concern: flush with the top of said sills, as shown. Be itknown that IJVILLIAM WV. GREEN, a The inside vertical face of the end sills is citizen of the United States, residing at Chicovered by the metal plate a (see Fig. 1,) and cago, in the county of Cook and State of Illithe inside corners of the structure strength- 5 nois, have invented certain new and useful ened by the angle-plates a.

The and the upper ends at are bent in the same upper inside corners of the outside sills are manner and rigidly secured to the ridge-bar 50 cut away, as at a so as to let in the flooring D, as shown in Fig. 5. The longitudinal I00 struts C, extending along through the junction of the side framing-posts and rafters, are of precisely the same construction as that of the transverse struts in the bottom structure, excepting the alternate socket cap plates, which are of the form illustratedin Fig. 7, in order to adapt the same to provide a suitable anchorage for the diagonal braces B. A detailed description of these companion struts will therefore be omitted.

The diagonal braces B are covered on their sides with the metal plates ff, as shown in Figs. 4, 5, and (5. It will be observed in Fig. 4 that the braces are of a less thickness than the posts, the difference being equal to the thickness of the metal plating, the posts being cut, as at f so as to let in the plates on the braces flush with the surfaces of the posts. The plates on the posts may or may not be equal to the width of the surface-which they cover. The diagonal braces are arranged at intervals and extend from the outside sills to a point just below the roof-struts and are rigidly bolted to the framing-posts. The lower ends of the diagonal braces are cut square, so as to have a full bearing on the horizontal metal shoes E, which are recessed into the outside bottom sills and turned upwardly at right angles, as at g, to provide a bearing for the toe end of the braces. The shoes E are under alternate ends of the posts. The angle ends of the metal plates covering said posts rest on these shoes, the fasteningbolts passing through both down into the sills, as shown in Fig. 5. The upper squared ends of the diagonal braces bear against the under side of the shoulder 9', formed on the socket cap-plate F, and the wood part out out to seat the lug 1 formed on the cap-plate F, the ends of the iron plates embracing said lug and being rigidly secured thereto by means of abolt or rivet passing through the aperture in the lug or lugs and correspondin g apertures in the metal plates on the braces.

The socket cap-plate F is of the elongated form shown, instead of circular, as are the other cap-plates used on the struts.

The outside covering of the car and roof consists of a number of metal plates G, bent to conform to the contour of the sides and root, and extend from the lower edges of the outside sills to the top of the ridge-beam, where the ends of the plates from the respective sides of the ear join, as shown in Fig. 2. The joining edges or joints of the plates G are covered by the continuous batten slrips H, secured in place by bolts 71, passing clear through from the outside and held by nuts on the inside of the respective posts or rafters. The batten-strips are concave-.011 their inner sides, as shown at h, Fig. 6, to permit of the insertion of some suitable packing to form a tight joint. The outside covering of the ends of the car will also be of metal put on in the same manner, and the inside lining may be of metal or wood, as circumstances mayrequire. Metal lining makes the structure substantially fire-proof.

Having thus described my invention, what I claim as new, and desire to secure by I.etters Patent, is-

1. In a car structure, the combination, with the outside sills, of the metal an gle-plates a a, the intermediate sills, the metal plates (1, a, the transverse struts connecting said sills, the transverse end sills, the metal. plate a, and the angle-plates a" a substantially as described.

2. In acar structure, the combination, with a wood sill or sills having the sides covered with metal plates, of a strut -rod passing through said sills, the chamber in the wood part surrounding said rod, and an aperture communicating with said chamber, whereby molten metal may be run into said chamber, substantially as and for the purpose set forth.

-3. In a car structure, the combination, with a wood sill or sills covered on the sides with metal plates, a continuous strut-rod passing through said sills and plates, a chamber formed in the wood part of the sills, and a mass of metal run into said chamber in a molten state, substantially as and for the pn rposc set forth.

4. In a car structure, the combination, with the outside and intermediate sills covered with metal plates, as described, of the continuous strut-rod, the socket cap-plates, the tube-sections having their ends inserted in said cap-plates, and the trussrod passing under the intermediate sills and anchored in the outside sills, substantially as described.

5. In a car structure, the combination, with the outside sills, of the posts, the longitudinal struts, the diagonal wood braces, and the metal plates covering the sides of said braces, substantially as described.

0. In a car structure, the combination,with the outside sills, of a metal shoe rigidly secured to said sills and having one end upturned, the Iramingposts, the cap-plates secured to said posts and provided with the shoulder g and the lug g and the diagonal braces extending from said shoe to said capplates, substantially as described.
